Internet applications provide personalized experiences, such as, a personalized greeting, by retrieving user information from a database maintained by a network content provider. A copy of at least some of the user information stored by the network content provider is saved on the user's computer by a user information manager for quick retrieval by one or more Internet applications. Synchronization between the provider database and the user database can be initiated in response to a request for user information received from a user side module, in response to the user information manager receiving new user information from another source and periodically by the user information manager.
